Our unique and proprietary bayonet design is second to none. It just out performs all others with design pressures to 40 barg and will not leak.
Simple to install, it will not leak and offers very low heat inleak. These are very important factors when choosing a vacuum insulated piping system. We offer the complete size range of on site butt weld options; ideal for cryogenic plant applications.

New Vacuum Jacketed Piping at VCCC

The Vacuum Jacketed Piping system for the new billion dollar Victorian Comprehensive Cancer Centre (VCCC) in Melbourne was designed and manufactured by Cryofin Pty Ltd.
On the 17th July this state-of-the-art facility was officially opened by U.S. Vice President Joe Biden. The Vacuum Jacketed Piping system is approximately 150 m in length and reticulates through two main cryo-storage areas and is designed to cater for up to 55 cryogenic ( 80K -190oC ) freezers. There are also manual fill points for non-pressurised dewars and a dual autofill station for pressurised vessels. The Cryofin Vacuum Jacketed Piping system is renowned because of its "leak free" bayonet design, overall vacuum integrity and ability to offer a complete and competitive turnkey package.
